Those who were thinking to put your xbox one in vertical position think again. Microsoft recommends you to keep it horizontal. Personally I prefer to put my console in horizontal position. Whats you take in this subject? Do you want to put xbox one in vertical position?

Microsoft told GameSpot today that the Xbox One won't support vertical orientation due to the inclusion of a slot loading drive.

The Xbox One won't support vertical orientation, and could damage the console, according to Albert Panello, senior director of product management and planning at Xbox.

Panello revealed to GameSpot at the Tokyo Game Show, "We don't support vertical orientation; do it at your own risk." He clarified that "it wouldn't be a cooling problem, we just didn't design the drive for vertical. Because it's a slot loading drive, we just didn't design it for both".

The Xbox One isn't the only system to feature a slot loading drive; both the PlayStation 3--original and slim models--and PlayStation 4 have a similar design, and users are free to orient those consoles horizontally or vertically without risking damage to the console.

Panello stated that Microsoft discovered that "we found, interestingly enough, that 80 percent of people, believe it or not, have their Xbox [360] horizontally".

The Xbox One is scheduled for launch in North America, most European markets, Australia, and New Zealand on November 22 this year, with follow-up releases in Japan and the remaining European markets in 2014.

With less of the system being on the surface, wouldn't you get better ventilation? Also, for the Drives in the system, we've had Blu-Ray for 7+ years now (other optical drives for much longer) I think getting discs to read while vertical shouldn't be a problem, unless they did a poor job constructing them. Hard Drives shouldn't even matter, since they're basically Laptop HDDs, which are made for any kind of awkward orientation. They also have sensors for determining any shocks which will prevent the head from crashing into the disks by parking them.
Perhaps they mean there would be more wear on the laser reading the discs, that's the only thing I see.
